TVLine.com’s Michael Ausiello of Ask Ausiello has posted a new How I Met Your Mother spoiler. For those wanting to remain spoiler free, do not read below.

Question: Any How I Met Your Mother scoop about Barney and Robin?
Ausiello: First comes love, then comes marriage, but in-between, there’s… cohabitation! In “The Fortress of Barnitude,” Barney — presumably in preparation for moving in with his fiancée — holds an open house in hopes of unloading his bachelor pad. (Cue flashbacks to one-night stands in 3, 2… ) Somehow, along the way, at least one potential buyer is given the impression that Ted and Marshall are a couple — and Lily, an intolerant homophobe. P.S. Hey, where is Future Robin’s wedding ring…?
